Falls And Bridges, St. John, N.B. Postcard
Falls And Bridges. St. John, N.B. (Tide at Slack Water) postcard. Divided back postcard. No publisher information on card. Card is postmarked June 28, 1907. The Reversing Falls at the mouth of the St. John River are a phenomenon resulting from the difference between high tide and low tide at this point in the Bay of Fundy being 29 feet. At high tide, the water in the bay is 14½ feet higher than in the river, resulting in water falling from the bay into the river; the reverse happens at low tide. The mouth of the river is only navigable at slack tide, as depicted in the postcard above.
